Question: I am a 62 year old male in good health. A little overweight (220lbs./ 6ft. 2 inches.), but prone to some ANXIETY. Resting blood pressure averages 125-130 over 70 -75. (Take 10 mg. Ramipril 1 x per day). Resting heart rate 55 beats per minute. I aerobically walk (and have walked for the last 20+ years). 3-4 miles a day, about 5 times per week at about a 15 minute mile. Cholesterol averages about 150 total; LDL-70, HDL-low 60's. (Take 5 mg. Crestor 1 x per day). For the last several months I wake up in the morning feeling vibrations in the central core of my body, that usually lasts about 10 seconds. My pulse rate is steady, but seems much faster for this short period - perhaps at 80-85 beats per minute vs. my normal rate of 55 or so. I'm not sure if the feeling of body vibrations result from the more rapid heart beat, but I suspect they might. Very quickly, within 10 -20 seconds, my heart rate returns to a more normal rate of 50-60, and does maintain a steady and regular rhythm throughout the time. On occasion in the past, I have notice my heart skip (mitro valve??), but this only occurs every couple of years. My question is do I need to be concerned about the briefly elevated heart rate that occurs only upon awakening, and is it possible this could be causing the short lived vibration feeling? Thank you.

Thank you Doctor for the quick response. One follow up question. Given that my vibrations only occur upon awakening, how likely is it that this might be an arrhythmia, vs. simply the effect of a faster pulse or simple anxiety. Thanks. XXXX
